One-loop contributions in the EFT for the $ΛN \to NN$ transition    [PDF]

Axel Pérez-Obiol, David R. Entem, Bruno Juliá-Díaz, Assumpta Parreño

We consider the $\Lambda N\to NN$ weak transition, responsible for a large fraction of the non-mesonic weak decay of hypernuclei. We follow on the previously derived effective field theory and compute the next-to-leading one-loop corrections. Explicit expressions for all diagrams are provided, which result in contributions to all relevant partial waves.
